Abstract
Abstract A ski binding to enable automatic release of the boot on falling, has a front stop element and a heel element each including a ball joint. The ball joint has a cavity into which a suitably shaped piston or piston and roller are urged by a spring, the tension of which is adjustable by a screw. The ball joint may have a second ball and socket detent in the heel element, also adjustable by means of a spring and a screw. The heel element includes a release lever, arranged so that pressure on the lever counteracts the action of the spring urged piston or roller.
